Managing Multiple Spanning Tree Instances
MSTP (Multiple Spanning Tree Protocol), as defined by the IEEE 802.1 standard, is used to map multiple VLANs
to a single Spanning Tree instance, otherwise referred to as a Multiple Spanning Tree Instance (MSTI).
Each MSTI is assigned an MST ID and a bridge priority:
• The MST ID is used to associate the MSTI with a VLAN.
• The bridge priority is used by all devices in the Spanning Tree topology to determine which device among
them is elected the root device or backbone. An ideal root device is one that is central to the network and not
connected to end devices.
For more information about MSTP, refer to
